To the Editor: Age-specific normal limits for a number of vital signs and physiological parameters have not been established in the elderly population. The limits for younger adults are not always applicable because of ageassociated physiological changes and the increase of interindividual differences with age. Regarding the respiratory system, there are few data on normal respiratory rate at rest (RR) and peripheral pulse oximetry values (SpO2), which are major parameters in clinical practice… 
Resting respiration rate predicts all-cause mortality in older outpatients
TLDR
The RRR was independently associated with all-cause mortality after adjusting for covariates, and this simple index seems worthy of consideration in further studies aimed at defining its predictive role in older people and in different settings.
Ventilatory defects and treatable traits in very elderly patients
TLDR
A high frequency of various TTs was found and the novel association between a restrictive spirometry pattern and cognitive impairment highlights the urgency of clinical research on this vulnerable age group.
Is everyone really breathing 20 times a minute? Assessing epidemiology and variation in recorded respiratory rate in hospitalised adults
Background Respiratory rate (RR) is an independent predictor of adverse outcomes and an integral component of many risk prediction scores for hospitalised adults. Yet, it is unclear if RR is recorded
Mean nocturnal respiratory rate predicts cardiovascular and all-cause mortality in community-dwelling older men and women
TLDR
In community-dwelling older men and women, polysomnography-derived mean nocturnal fR ≥16 breaths·min−1 is an independent predictor of long-term cardiovascular and all-cause mortality.
Comments for better understanding of the study “Aging is independently associated with an increasing normal respiratory rate among an older adult population in a clinical setting”
TLDR
The authors found that age was correlated significantly and positively with the respiratory rate and pulmonary diseases showed significant negative correlation with respiratory rate in older patients aged between 59 and 100 years.
Assessment of respiratory flow cycle morphology in patients with chronic heart failure
TLDR
Investigation of the significance of a number of time domain parameters for characterizing respiratory flow cycle morphology in patients with CHF concludes that morphologic analysis in the time domain is useful, especially when short signals are analyzed.
Piezoelectric Sensor-Based Continuous Monitoring of Respiratory Rate During Sleep
TLDR
A novel, easy-to-use, respiratory rate-monitoring sensor made of stretchable piezoelectric material that can be used conveniently at home as well as in a clinical setting and was effective in people in all age groups.
Estimation of breathing rate in thermal imaging videos: a pilot study on healthy human subjects
TLDR
A new robust approach, based on data fusion, to remotely monitor BR using infrared thermography (IRT), which considers not only temperature modulation around mouth and nostrils but also the movements of both shoulders and demonstrates the capability of IRT to capture varied breathing disorders, and consecutively, to assess respiratory function.
Calibrating a non-contact and low-cost respiratory monitoring system based on Digital Correlation Technique
TLDR
An effort to develop and calibrating a non-contact and low-cost respiratory rate monitoring system, based on digital image correlation technique using a used Microsoft Kinect camera, which was designed as a hands-on training for last year student.
